Release Notes: An option for specifying the exact file to be used was added, to allow sharing of file(s) between threads or processes. IO syncing was integrated into a normal read/write path. Various IO engine bugs were fixed. The documentation was greatly improved (including a HOWTO with detailed parameter information). The command line and job file parsers were unified for easier scripting. Unaligned IO is supported. A fsx-linux sample simulation job file was added. A crash with random map for unaligned file sizes was fixed. Bandwidth info was added to status print. Build fixes were made for non-Linux platforms. Support for controlling read and write buffer sizes separately was added.
Release Notes: Adds JSON output for client/server. A fix for Windows build breakage in the previous release. A fix for ioengine specific options. Adds support for O_ATOMIC atomic writes on Linux. A failsafe check for realloc() failure during logging. A fix for a Solaris thread problem. Various man page and documentation updates. A fix for a crash on PowerPC without the mfspr instruction.
Release Notes: This release adds basic support for an ACT (aerospike) profile, fixes atomic write support, adds various parsing fixes, makes a big revamp of the included graphing support, makes the IOPS log includes bandwidth, adds support for specific randomness settings for both reads and writes, adds support for random vs. sequential blocksize settings, fixes a potential verification failure, and adds multicast support for the net ioengine.
Release Notes: Integration of the gfio GTK frontend. Better Android integration. The initial file fill honors data compression settings. An option for controlling randomness of I/O (percentage_random) instead of being fully random or fully sequential. Fixes a bug in uneven pattern sizes for verification. Various other important fixes.
Release Notes: This release adds an --eta-newline option to insert ETA new line at fixed intervals. Fixes for the CPU clock, notably PPC. Fixes for workloads with read/write file locking. A fix for skewed latencies with rated IOPS. Fixes a bug with block sizes varying more than 64x. Improves the LFSR implementation. Fixes missing JSON bandwidth output. Various fixes for the Android platform. Uses ginstall on Solaris. Fixes man page installation. Other bugfixes and improvements.
Release Notes: Autodetect features with a new configure script when building. Improve ETA for some workloads. Support for verify mode that requires no metadata, greatly reducing memory requirements for big device verify workloads. Ensures fsync is always done, even for direct/raw I/O (if asked to). Support for unified read/write/trim reporting. A few axmap and cpuclock bugfixes. Fixes zones and numjobs used together. Adds support for idle profiling, showing idle system CPU when running a workload. Various Windows fixes. FreeBSD now supports CPU affinities. Many other fixes; all users should upgrade.
